Don’t Buy A Stupid Stretch Wrapper 4: YOU ARE IN CONTROL

So, you have taken the necessary steps, but how do you know nothing will change with your new method?

Lets review the steps taken so far.  You have DEFINED the problem and admitted that you could be better at wrapping.

We walked through MEASURING your current methods to establish a baseline.  Additionally you used the ISTA to ASTM methods to ANALYZE your systems.

Then you IMPROVED your methods (and hopefully wrote the specifications for your packaging).

Now to CONTROL the changes.  There are several methods to verify that the settings of the machine are maintained.  They could range from on board monitoring systems, to cut and weighs, to continued containment testing.

The theory of all is that by wrapping consistently you will utilize the same amount of film on identical pallets.  By incorporating any of the methods into a customer’s PM routine, you will use consistency as your control.

Lets expand on the various methods of measuring and how they work: The first is ON BOARD MONITORING.  This system will measure film as it’s applied to the load and report back to the customer via close based servers.  This is the best and most accurate method as it will allow customers to view the data in multiple ways.  It could be linear footage, amount of stretch, cost per load…..the list goes on and on.

The second method is the STRETCH FILM CUT AND WEIGH TEST.  The principle here is the same, but the control is the weight of the film.  You purchase film by the roll, but the resins that make the film are actually sold by the pound.  Using weight is an excellent method to verify cost per load and consistency of wrap.

The last method is CONTAINMENT.  This method is also very accurate as every revolution of film on a pallet will increase the containment force.  By measuring containment, you can verify that your wrapper settings have remained set to specifications.

The last method that can be used is a visual inspection of machine settings; but know that if there has been a film change, or as the machine wears, it will become inconsistent in performance. Different films stretch at different forces; putting on a softer film but leaving the machine at the same mechanical settings will increase film yield but decrease containment force.  Wear, well that speaks for itself, all things eventually wear.  The more play in your roll carriage bearings, the more film can slip through your roll carriage costing you money.  As a side note, this is also an issue with some film monitoring systems.  Because of how film is measured, they cannot account for slip.

Well, that wraps up our “Don’t Buy a Stupid Stretch Wrapper” series.  I hope that you enjoyed it and feel slightly smarter than you did prior to reading this.

DBASSW Bonus: The Magnetic Film Finger

We interrupt your regularly scheduled program to bring you this important announcement from our sponsor: HIGHLIGHT INDUSTRIES.

So you have been trucking along reading about how to improve your pallet wrapping and now a commercial, no fast forwarding through this like its on your DVR.  This is that infomercial that may actually help you, so don’t consider this a commercial, think of it as sponsored learning.

While we spent time talking about the method of adjusting your machine, there are some additional tools that you may want to make note of.  Since I try to have some fun while writing bear with me while I channel my inner Ron Popeil.

I’m not going to paddle a screen door bottomed canoe around a lake that has been sprayed with a new tangled sealant, or spray paint my head yet, but wait, there’s more!

From the inventor who brought you such great things like Dual Powered Hydro-Stretch, Revolver Wrappers, Synergy Wrappers and everyone’s favorite the Predator Wrapping Family, we have the revolutionary new craze that is taking stretch wrapping by storm:  The Highlight Industries  Magnetic Film Finger, for when dialing in your containment force is too difficult to do because you just cant seem to get enough force without breaking the film!  Magnetic Film Fingers (MFF) are not made of space age materials and are not coated with impregnable Peruvian Yak Hair to limit wear.

But they are easy to use and their benefit is unmatched.  Mounting to most steel, they can be positioned on roll carriages and bases to provide a small roll of film which is more resistant to tear and propagation.  It’s simple, place the film finger in a position on your machine which allows for the roles end to fold the edge of the film over on itself.

 Seeing is believing, so watch below to see the MFF in action:

 

And watch here to see the MFF used as a bottom roper:

Also know that after your testing is complete, Highlight Industries can provide you a set of adjustable permanent fingers for some styles of machine. Machine sold separately.

 

We now return you to your regularly scheduled Blog.

DBASSW Part 3: Improving your Method

Improving you method.

Are you having shipping damage?  Most everyone does, so if you answered no to the question: Congratulations! You are an exception, or perhaps ignorance is bliss.  Perhaps you should be filling the blogosphere with your wisdom…..or you can continue reading.

So now you are armed and dangerous with your Test Kit and you have the Highlight Stretch Tools Application on your Mobile Device.  Now what?  Well, you may ask yourself: “Self, this is great information but how do I use it?”

From here on it it may get challenging, but hey, you are up to the task! You already have shown a willingness to learn by reading our Blog!  Compare your containment test numbers to the numbers from the Highlight Stretch Tools App, Do they match?  In most cases, they do not.  I would guess that the Stretch Tools App has given you a higher number than you recorded using the ASTM D-4649-03 Annex A1 approach .  That is okay, we can fix that.  If the Stretch Tools App has given you a lower number than you record, great.  Again, you may be an exception but also know that you could improve also.  In fact, you may have too much film on your product and there could be a savings to be had here.

uneven-film-application

In both cases you can modify your wrap patterns (number of top and bottom wraps or the amount of film overlapping itself going up and down and turntable speed) and wrap force (the film force dial on the machine that makes the film loose or tight).

By adjusting these settings you will dial in your machine to match the Stretch Tools App.  There is some art to it but stick with it, you are about to become your company expert.  After you make a change, wrap a pallet, measure using the ASTM method and tools and see where you are against the ISTA (Highlight Stretch Tools App).  Once you are dialed in on your machine you are on the path to damage reduction or film savings!

Here’s a novel idea, write up your company’s packaging specifications based upon your findings.

Don’t Buy a Stupid Stretch Wrapper: 2

ESTABLISHING YOUR BASELINE IN STRETCH WRAPPING.

In part 2 we are going to talk about establishing a baseline. Perhaps you have heard some of these statements: “Without Data you are just another person with an opinion” – Dr. Deming.dr deming stretch wrap

Or the words of Lord Kelvin, “If you cant measure it, you cant improve it.”
kelvin stretch wrap

First, lets define containment force with regards to pallet stretch wrapping. When you wrap your pallet with stretch film, you have the decision of how much force you want that film to squeeze your pallet with. You can wrap the pallet very loosely, which will allow for only a dust cover, or you can really pull the film tightly. The pressure that the film applies to the pallet is containment force.

Read more about containment force and stretch film properties HERE.

Unlike others who design special tools to measure containment, Highlight Industries conforms to ASTM D4649-03 Annex A1. This is a documented and repeatable method to measure containment on your pallets. (Please note that we also offer tools to allow you to measure your containment).

You may ask yourself, “Self, why would I want to use this method instead of others who may incorporate a cool gadget?”

The answer is simple: Highlight Industries helps you develop your packaging standards. Isn’t it important to have a nationally recognized living document that is available to provide your customers on exactly what you have done? Instead of them having to buy custom measuring tools that may not be clearly documented in their methodology, and could also allow for user variances.

For more information and tools to help you measure your containment, please contact Highlight Industries. Tune into the same Bat Channel and at the same Bat Time to read Part 3 of our Series….Improving your methods.

Don’t Buy A Stupid Stretch Wrapper

Don’t buy a stupid stretch wrapper (from a stupid stretch wrapper company)!
Part 1

They all go round and round round and up and down right?
Wrong!

How you stretch wrap your pallets will make or break your customer’s relationship with their customer, and ultimately their relationship with you!

Image result for business relationships

At Highlight Industries, we pride ourselves in taking a scientific approach to stretch wrapping pallets. Over the years, salespeople have all been trained that if pallets fail, the solution is to put more wrap on the pallet. Maybe more at the top, maybe more at the bottom; perhaps, eliminate the vibration in the middle. uneven stretch film application

This ‘solution’ can be inconsistent, inefficient, and potentially costly. There has never been a “this is how you do it” fix… until now.

Introducing the Highlight Industries stretch tools App!

Among other things, such as a mil to gauge convertor, diagonal calculator, 20 vs 30 film comparison, cost to wrap, etc,  the Stretch Tools App has a containment force calculator.

containment force calcuation

You may ask yourself, “self, what does that do?” The answer is: Highlight Industries Containment Force Calculator will take important criteria (load value, dimensions, distance to be shipped, etc) and deliver an estimated containment requirement (the force that provides to hold your products in place), as well as the estimated amount of film that should be used to wrap the load and achieve this containment requirement.

Containment force

The Stretch Tools App eliminates the guess work when wrapping. You’ll always have the correct amount of film to keep your products safe; not so little that it falls apart, and not so much that you’ll be wasting money over-wrapping.

This app is available in Apple and Android versions.

So while other companies try to tell you the importance of containment, Highlight Industries shows you the amount required……very smart!
